Dry Carbon Fiber Side Skirt Extensions – BMW G82 & G83 M4 Coupe (2021+)

2021–2024 BMW M4 G82 / G83 Side Skirt Extensions – Pre-Preg Dry Carbon Fiber

Upgrade the side profile of your BMW G82 or G83 M4 with these pre-preg dry carbon fiber side skirt extensions. Supplied as a handed pair, they extend the factory rocker lines for a lower, more aggressive stance with a premium exposed-weave finish.

Build

• Material: Pre-preg dry carbon fiber in a 3K twill weave — the resin is pre-impregnated into the weave under controlled conditions before curing, giving lightweight durability, a consistent weave, and a lighter finished component than standard wet carbon
• Manufacturing: Precision-moulded using 3D design and CNC machining
• Surface finish: High-gloss protective clear coat with a UV-resistant surface that helps maintain long-term finish quality
• Configuration: Supplied as a handed pair (left and right)

Design & Finish

• Aggressive stance: Extended skirt profile sharpens the lower body lines and visually lowers the car for a more planted look
• Carbon aesthetic: Refined 3K twill dry carbon weave and high-gloss finish deliver premium contrast against the factory paint
• Factory-style integration: Precision-molded for clean alignment with the factory body lines and rocker panels

Fitment

• 2021–2024 BMW M4 Coupe (G82)
• 2021–2024 BMW M4 Convertible (G83)
• Fits the factory rocker panels only — not compatible with aftermarket configurations

Package Contents

• 2 × carbon fiber side skirt extensions (left and right)
• Mounting hardware

Installation

• Screw-mounted: Secures with the included mounting hardware — no major modifications required
• Drilling required: Screw fixing pierces the rocker panel, so this is a permanent modification rather than a reversible fit
• Check orientation: The extensions are handed — confirm correct left and right sides before fitting
• Alignment: Dry-fit both panels and check height and fore-aft position match on each side before driving any screws
• Professional installation recommended for correct positioning, symmetrical alignment, and a clean finish along the full length

Before You Install

• Confirm your car is a G82 M4 Coupe or G83 M4 Convertible (2021–2024) before ordering
• This is a permanent, screw-mounted fitment — dry-fit both panels and confirm placement carefully before driving any screws, as holes cannot be undone
• Dry-fit both panels first — any difference in height or position between sides is visible along the car
• Side skirts sit low and are exposed to kerbs and driveway ramps — take care when parking
